7 RUNNING THE MOTOR
Before giving RUN command, motor parameters have to be set and auto tuning has to be performed.
7.1 Motor parameters
In table 7 motor related parameters are shown, please set motor parameters following same order:
Function Meaning Recommended setting Remarks
P01 Number of motor poles Depends on the motor
Depends on the motor
F03 Motor’s maximum frequency (Hz) 50 Hz
F04 Motor’s synchronous frequency (Hz) 50 Hz
F05 Motor’s rated voltage (V) 400 V
F11 Overload detection level (A) Same value than P03 Depends on the motor
F42 Drive control selection 1

P06 Motor’s no - load current (A) 40 % of P03 -
P07 Motor’s stator resistance (R1) in %

P12 Motor’s slip frequency (Hz) Depends on the motor Check NOTE
Table 7: Motor related parameters
NOTE:
• If motor’s speed is 3000 rpm, means that motor has 2 poles, in consequence P01=2.
•
If motor’s speed is 1500 rpm, means that motor has 4 poles, in consequence P01=4.

7.2 Step by step auto tuning procedure
After setting correctly motor parameters, next step is to perform an auto tuning:
1. Set P04= 1 (After auto tuning is finished, it will be se automatically to 0).
2. After selecting MAINTENANCE operation give RUN command (UP or DOWN). Keep RUN command
until inverter’s keypad shows that auto tuning is finished.
Auto tuning mode 1 (P04=1) is static, it means that motor will not turn.
Auto tuning process will automatically finish. When it is finished p06 parameter is shown.
If inverter trips er7 during auto tuning, please check chapter 11.
